[asterisk-dev] Text-to-Speech and Speech-to-Text

[Dan Cropp]

Thank you Ben.

Looking at the TTS, would that language property be language and country?  Example en-US, en-GB, etc.
Will we use SSML to specify a specific voice for the language?  Examplt, Amazon Polly en-US language supports 4 female and 4 male voices.  Or might this be an additional parameter (similar to the language)?

Will there be a mechanism to stop the TTS on one stream when speech to text detects someone speaking?  Many people will interrupt automated phone systems.  Example, the system answers the call and plays something, a person familiar with the system will start speaking and they expect the TTS/prompts to stop playing.

Have a great day!
Dan

Hello everyone,

The Asterisk team has been working on planning better text-to-speech and speech-to-text functionality for Asterisk. We’ll be using a speech service in conjunction with an external application that connects it to Asterisk. More information on the protocol used for this and the overall project can be found here:

https://wiki.asterisk.org/wiki/pages/viewpage.action?pageId=45482453

After reading the wiki page, if there is anything you feel could be improved, we’d love to hear about it. The goal for the protocol is to make it generic enough to where we would be able to use it for other things besides text-to-speech and speech-to-text in the future. This means it should remain as simple as possible. We tried to come up with basic scenarios and give examples of what it might look like, but this may not cover all bases. If you see a case that the protocol would not be able to handle, we want to hear about that, too!
